FERRULE-SHAPING MACHINE.

Application filed November 3, 1920. Serial No. 421,42'9.

T (67 Z to 710m it may concern Be it known that I, WILLIAM E. YOUNG,

a citizen of the United States, residing at Baltimore, in the State ofMaryland, have inventeda certain new and useful Improvement in Ferrule-Shaping Machines, of which the following isa specification.

My present invention relates particularly to a ferrule-shaping machine,adapted to be operated by power.

An object of my invention is the application of mechanical power in thegiving of a'desired configuration to closed metallic bands, or the like,and especially the shaping ofbands or ferrules such as are commonlycomprised in the heads of paint brushes used by house painters.

Brushes of the type referred to are usually provided with a handle ofwood or the like, at one end of which is secured a body of bristles, ortheir equivalent, and the band or ferrule referred to, may be comprisedof a section of drawn metal, or may be formed by cutting transversely ahollow cylindrical body or by uniting the ends of a suitable piece ofsheet metal.

The ferrule referred to, when used on a paint brush, is typically soemployed as to secure, hide, and protect the joint between the handleand the fibres, or the like, that constitute the head of the brush. 7

Before being put in place on the head of the brush, such a band isordinarily in need of a final shaping, which shaping must of coursesecure a fairly accurate correspondence with the transverse sectionalconfiguration of the brush upon which the hand is to be used. As brushholders are manufactured not only in large quantities but inn 4 greatvariety of sizes and styles, the foregoing implies the need of acapacity for alterations, by adjustment or substitution,

in those elementsof the band-shaping ma chine which determine the finalsize and configuration of the band; and the objects of my inventioninclude a facilitating of such adjustments or substitutions; and theobjects thereof also include the providing of a machine, capable of awide variety of uses in addition to those mentioned, which shall becompact, rugged, rapid, safe, attractive in appearance, and providedwith a means for the application of power and the immediate and easycontrol ofv an operative who, the desired adjustments or substitutionshaving been made, need only place the band to be shaped upon the workengaging elements hereinafter described, and then move a lever to secureapplication of power from an outside source thereto.

Further objects of my invention will appear from the detaileddescription set forth hereinaftenand, while my invention is capable ofembodiment in many different forms, for the purpose of illustration 1have shown only certain forms of my invention in the accompanyingdrawings, in which:

Fig. 1 is a front elevation of a preferred embodiment of my invention.

Fig. 2 is an end elevation as viewed from the left of Fig. 1, but notincluding the casing 30, nor the drive pulleys 31, 31', shown at theright of Fig. 1,

Fig. 3 is a vertical longitudinal section corresponding to Fig. 1, and,for the most part, in the plane of the main drive shaft, that is to say,on line 3-3 of Fig. 2.

Figs. 4 and 5 are vertical transverse sections, on lines l- 1, and 5-5respectively of Fig. 1, looking in the direction of the arrows.

6 is a plan view. I

In the form of my invention herein shown, there is a hollow maincasting, frame, or housing 24:, which may restupon any suitablefoundation, and which in turn preferably sup-ports both thework-engaging parts 14, 1 1 and the actuating mechanism therefor.

Although any suitable source of power may be used, I have herein shown aspeedreducing drive mechanism comprising tightanddoose pulleys 31 and31, the outermost pulley being preferably secured, by means such ascollar 33, against lateral movement on the shaft 18. The shaft 18, shownas carrying only a gear 19, preferably keyed thereto, may be supportedin any suitable way, as by (1) the double bracket 29 (carrying also themain shaft 32), and (2) a suitable ring or rings for securing one orboth ends in casing 24.

The work-engaging parts or posts 14, 1% maybe of any desired external ortrans verse configuration, and one or both of them may be removably andadjustably secured, to facilitate either a change in the form andcurvature given to the ends of bands worked upon. or a change in thedistance therebetween-the latter change being made whenever, therequirements as to thickness and type of brush remaining unaltered,there are to be handled successive batches of bands or ferrulesdiffering only as to the width or longer transverse diameter of thebrush heads in which or upon which they are to be used.

While it will be obvious that the desired shaping action might beattained by a suitable movement on the part of either or both of thework-engaging posts referred to, I have shown in the drawingsa fixedpost l l as secured by machine screws to the main frame 24:,appropriatemeans being, however, provided for guidance and a justment as well asreciprocation of the corresponding post 14.

It being desirable that the work-engaging posts 14, 14 shallbelconveniently positioned for the placing and removal of successivebands or ferrules to be shaped or stretched thereby, I have preferred tomake provi sion such as an undercut channel in the top of the maincasting 24:. In this channel I have shown a reciprocating element which,for convenience, I hereinafter designate as carriage 21, and which isshorter than the mentioned channel in which it moves. It mayconveniently be given the desired alineinent andsecurity in said channelby means such as the adjustable and removable spacing plate or gib 12.Said gib in turn may be secured in any suitable manner, as by pins 26,each preferably provided with a lock nut or nuts 39, the reciprocatingcarriage 21being free to slide relatively to the said plate or gib 12. v

To the rearward end of the carriage 21 I prefer to secure, by anyconvenient means, such as bolts orscrews 40, a threaded bearing element13, to receive a corresponding long adjusting screw 8, to one end ofwhich screw I may secure suitable actuating means such as the crank 28,shown as provided with handle 15, the other end of the shaft of screw 8being preferably provided with a circumferential groove to securethereto, by means such as pins 41, a slidable element 11 carrying thework-engaging post 1&, which may be removably secured thereto forconvenient substitution, by means such as.

screws 42.

If desired, a set screw 43 may be provided in the threaded bearing block13, to secure in any adjusted position the mentioned screw 8, thepreferred construction being such that whenever, to effect the expandingor shaping of a band placed over the posts 14, 14, the carriage 21 shallbe reciprocated, the crank28 and all associated parts must reciprocatetherewith.

To effect the desired reciprocation of the carriage 21, any convenientmeans may be employed, and in the present embodiment of the invention Ihave imparted the desired IGCiPIOCiLtiIlg motion by means of an arm 25,shown as depending from the plate l3, which plate maybe secured, bymeans such as screws 44, to the bottom of the carriage 21. The arm 25preferably carries means such as pin 17, which may be provided withrollers 22, and may be secured by a set screw 4l5, for effecting contactwith cam grooves in discs 1., shown as rigidly mounted on the main shaft32, which is adapted for occasional or intermittent rotation.

As shown, shaft 32 may have one of its bearings in the bracket 29,screwed to the main frame'or housing 24, and its other end mayadvantageously be provided with a friction collar 10, preferably keyedthereto and shown as capable of rotation in a split bearing, providedwith adjustable means for a braking effect, such a bearing being shownat 3, secured at 38, the lubrication of the shaft being, however,provided by means such as Winlrley oiler 35, with lubricating sleeve 5,the function of the described brake organization being; a promptretardation in the main shaft 32, and of the described reciprocatingmeans driven therefrom, when ever the power shall be thrown off from thesaid shaft, as may be done by means hereinafter described.

On the main shaft 32 there are mounted any suitable means fortransmission of power thereto from the gear 19, heretofore mentioned. Itwould obviously be possible to transmit suitable motion to the shaft 32in a continuous manner, thereby occasioning a rythmical reciprocation ofthe post 1% relative as to the post 14, the operative being thenexpected to utilize, for the placing and removal ofthe bands to bestretched, those intervals when the posts are relatively close together.I, however, prefer to provide means such as a clutch and stop mechanismfor transmitting motion to the main shaft 32, and thereby to the postit, the said clutch being preferably under manual control through meanssuch as lever 2, herein shown as pivoted to the main frame 24, andnormally held in its rearward or rest position by means such as thespring 16.

In the construction shown, the forward movement of the lever 2,elevating the hook 426, and causing the engagement thereof with a pin orstud 4L7 on the cam-faced lever 48, pivoted at 19, and depressed by thespring 18, permits the curved or practically circular leaf spring 50 toforce the pin 51 into the path of the heads of the bolts 20, which headsproject from the face of idlly revolving effect clutch gear 27,constantly driven by the gear 19 (and preferably protected by a casing30) to thereby cause the clutch element 52 (carryin the tripper torevolve therewith and to rotate the main shaft upon which it ismounted-all for the purpose and with the efiect above described.

It is in order to limit the effect of the movement of the lever 2 to asingle reciprocation of the post lt that means such as the mentionedtripper 53 are provided, and this tripper is so placed on the clutchelement 52 that, even if the operative happened to fail promptly torelease or return the lever 2, the first revolution of the clutchelement 52 willautomatically, by contact with the said tripper with aface 54: of the hook 46, cause a disengagement of the lever from thestud on the cam-faced lever 4L8,the depression of which, under theaction of the spring 18, will, by the engagement of the cam face withthe notch in the pin 51, cause a retraction of said pin and thereby adisengagement of the clutch, all parts being incidentally returned totheir original position.

From the foregoing it Will be apparent that, upon the placing of a bandover the posts 14 and 14, and the pulling of the lever 2, there iscaused a single reciprocation of one of the posts, and the parts arethereafter brought promptly to rest in a position suitable to arepetition of the described operation.

What I claim is:

1.
